A study published in Scientific Reports evaluates non-thermal plasma as a tool for disinfecting indoor air and reducing particulate matter. The technology, which generates reactive species at near-room temperature, has been proposed as a complement to filtration and ventilation strategies in spaces where bioaerosol load is a concern.
The paper measured reductions in both microbial contamination and particulate concentrations under controlled conditions. While the work does not establish non-thermal plasma as a replacement for source remediation in water-damaged buildings, it adds to the growing literature on engineering controls for indoor air. The authors note that practical deployment will depend on ozone byproducts, energy use, and occupant safety considerations that vary by device design.
